Review on CDI Electronics 511-9766 Enclosed Adjustable Spark Gap Tester - 8 Cylinder Engine Diagnostic Tool by Chris Goldsby

Revainrating 3 out of 5

Good quality, sometimes barely visible spark

Easy to set up but hardly visible spark on outboard motors, especially in the sun. While I like being able to check multiple cylinders at once, it's much quicker.

Pros
  • Tools and equipment
Cons
  • Slightly dented
